SNAP-HOOK.

SPECIFICATION forming part of Letters Patent No. 428,799, dated May 2'7,1890.

Serial-No. 337,973- (No model.)

the art to which it appertains to make and use the same.

My invention has for its object to provide a combined snap-hook andswiveLthat shall be strong and practically indestructible, and in whichthe cost of production shall be reduced to the minimum.

With these ends in viewI have devised the simple and novel constructionof which the following description, in connection with the accompanyingdrawings, is a specification, numbers being used to denote the severalparts.

Figure 1 is an elevation of a piece of chain illustrating the use inconnection therewith of one of my novel snap-hooks; Fig. 2, a viewillustrating the steps in the process of making the swivel-heads; Fig.3, an elevation of a snap-hook detached, the swivel-head and base of thespring being in section; Fig. 4, a View of the spring detached; Fig. 5,a sectional view showing two of the swivel-heads used together to form adouble swivel; and Fig. 6 is a View of the shank and washer of a doubleswivel detached.

The chain forms no portion of my invention, it being of course apparentthat any suitable chain may be used, although in practice I preferablyuse, and have illustrated in the drawings, the chain described andclaimed in Letters Patent No. 359,054, granted to me March 8, 1887.

My novel snap-hook consists, essentially, of a hook, (denoted by 1;) aspring, (denoted by 2;) a swivel-head, (denoted by 3;) a washer withinthe swivel-head, (denoted by 4,) and a rivet through the ears of theswivel-head, (denoted by 5.)

The bow of my novel snap-hook is preferably fiattened on its sides, asat 10, so as to give the greatest possible strength at just the pointwhere it is required, and the shank, which I have denoted by 1, issquared at the end, as clearly shown in Fig. 3. The spring is formedfrom a T-shaped blank, (see Fig. 4,) the arms forming the base of thespring being clasped around the squared end of the shank, the inner endof the base of the spring when clasped about the shank resting against ashoulder 9 at the inner end of the squared portion thereof. Theswivel-head is preferably made more or less cupshaped, as shown in thedrawings. WVhen formed to shape, each swivel-head is provided with apairo1": ears 6, having holes 7 through them, and at the bottom of 1 eachhead is a round hole 8 of just sufficient diameter to receive thesquared end of the shank and permit the latter to turn within it. Thewashers which lie within the swivel-heads are provided with squaredopenings 11, which just receive the shank, so that the washer must turnat all times with the shank.

The parts are assembled as follows: The base of the spring is clampedabout the squared end of the shank, the inner end of the base restingagainst shoulder 9. The end of the shank is then passed through theswivel-head, awasher having a squared opening placed over the shankwithin the swivelhead, and then the end of the shank isheaded down uponthe washer, as at 12. This leaves the swivel-head held between thewasher and the outer end of the base of the spring, but free to turnupon the shank. This locking of the washer against turning on the shankinsures that all the wear shall be upon the washer, thereby preventingthe possibility of the heading being worn away and allowing the parts tobecome separated. The chain is connected to the snap-hook by placing theend link between ears 6 of the swivel-head, and then passing a rivet 5through both ears and the link and heading down the rivet upon the outerside.

Having thus described my invention, I claim a A snap-hook consisting ofa hook proper having a squared shank, a T-shaped spring, the base ofwhich is clasped about the squared end of the shank, a swivel-headhaving a pair of ears and a round opening through which In testimonywhereof I :Lffix my signature in the shank passed, a washer in the baseof presenee of two witnesses. the swivel-head having a squared openingto l a fit the shank, so as to turn with it, said shank RH HARD A IRTUL5 being headed down upon the Washer, and a \Vitnesses:
